MTL - Eternal Reverence - Chapter 1189 Ghost in the city

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them. Little do they know that knowledge is full of lies and energy is the root of destruction. Us, mages, have mastered travelling through space and time. We are invincible, we can turn worlds into dust and you, mere ants, will be wiped out with no trace.

-Mage Adam

Twelve zodiac animals represented the months of the Lunar calendar. No one was aware,however, that these twelve representations were Guardian Gods. These twelve positions were passed down the twelve patron bloodlines. They possessed the ability of the zodiac guardians and silently protected the East.

In the East, the auspicious Qilin, possessing royal blood, descended, reigning over the Twelve Zodiac Guardian Gods, who devote all of their power into protecting the East.

A ruffian Qilin, an Earth that transcends all expectations, a legendary city, and the patronage of the Zodiac animals together create an unforgettable novel.
